Democrats on the House Oversight and Reform Committee announced Tuesday they are launching an investigation into the Trump administration’s dealings with Saudi Arabia after several whistleblowers expressed concern about efforts to sell the kingdom nuclear technology.

The announcement came in conjunction with the release of a report by committee staff that said senior White House officials pushed for the sale of nuclear technology to Saudi Arabia despite warnings from ethics advisers and national security officials to stop.

“Based on this snapshot of events, the committee is now launching an investigation to determine whether the actions being pursued by the Trump administration are in the national security interests of the United States or, rather, serve those who stand to gain financially as a result of this potential change in U.S. foreign policy,” the report said.

To continue the investigation, House Oversight and Reform Committee Chairman Elijah Cummings (D-Md.) sent letters to several people and organizations involved with promoting the plan, including the White House, the CIA, the Flynn Intel Group, IP3 and the departments of Commerce, Defense, Energy, State and Treasury.
